From 9am AEST Wednesday 4th February 2026, the AWA will release the first official Wagyu Breeding Values (WBVs), marking the beginning of a fully independent, Wagyu specific evaluation system designed for the modern Wagyu industry.
This milestone reflects years of preparation, a transformed dataset, and a deliberate shift toward a framework built exclusively around Wagyu animals, Wagyu production systems and Wagyu economic drivers.
What WBVs Represent
WBVs describe genetic differences between animals in the same way EBVs do, but they are powered by Wagyu‑specific data and models.
WBVs draw on:
- A fully integrated, multi‑trait genomic evaluation
- The world’s largest Wagyu genotype and phenotype dataset
- High‑density genomic information across animals with varying Wagyu content
Most WBVs remain highly correlated with their EBV counterparts for major traits such as growth, carcase weight, and marble score. Where re‑ranking does occur, it reflects enhanced Wagyu specific trait relationships and the use of additional data.
How WBVs Are Now Possible
This launch is the outcome of a multi year system renewal program.
In recent years, AWA’s dataset has expanded dramatically:
- Total animals analysed have nearly tripled
- Genomic coverage has grown by more than 600%
- Carcase records, especially from MIJ camera data, have increased sharply
With this scale and maturity, AWA can now:
- Estimate genetic parameters directly from Wagyu data
- Run an independent evaluation pipeline
- Introduce new traits without external constraints
- Deliver results weekly, with faster turnaround from DNA test to publication
Ongoing Updates & New Information Releases
The release is the first step.
Over the coming days and weeks, AWA will continue to publish new information to support members, including:
- Detailed WBV documentation and trait descriptions
- Educational guides on interpreting WBVs
- Updated trait explanations, including Maternal Weaning Weight, Eye Muscle Area, Marbling Fineness and Net Feed Intake
- Index updates reflecting WBV inputs
- Further analysis of data being used in the evaluation
As additional data is incorporated into the system, updated WBVs will be published in line with AWA’s independent evaluation cycle.
Submitting Data Going Forward
The AWA will continue to support members in submitting performance, genomic, and carcase data into the WBV pipeline, and will provide updated guidance to ensure members have clear visibility of how their data is incorporated into each WBV run.
Upcoming communication will outline:
- How animal performance records flow into the WBV evaluation
- Requirements and reminders for genomic sample submission
- Pathways for carcase and MIJ camera data
- Timelines for data cut‑offs ahead of each weekly WBV run
Because WBVs are generated independently by AWA, this guidance will help members understand how their data contributes to the evaluation, while ensuring smooth integration and timely processing within the WBV system.
